A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning.  相似文献

Misidentification syndromes have been studied from a variety of perspectives, including phenomenological, biological, and nosological approaches. More recently, misidentification syndromes have been studied from a psychiatric-legal perspective, especially with regards to the problem of dangerousness. Capgras syndrome and other syndromes of misidentification can lead to hostile mood and subsequent physical violence. Little attention has so far been devoted to children as the objects of the psychotic person's misidentification delusion(s). We provide a review of cases from the anglophonic literature that have children as the misidentified objects, add three new cases, and then discuss the relationship between misidentification and potential harm to these children.  相似文献

Mandatory reporting legislation has been adopted in every state to insure the protection of children from maltreatment. These statutes have become a significant factor in the lives of mental health professionals who work with children and families. Thirty psychotherapists who had made a recent report of child maltreatment on a client in treatment were interviewed about their experiences with reporting and the consequences of reporting for therapeutic relationships. Several potentially problematic consequences and dilemmas were identified by the therapists, including immediate and long-term effects on the therapeutic alliance and course of therapy, and conflicts of interest in working with children and families.  相似文献

This article analyzes the enforcement practices of the Investment Industry Regulatory Organization of Canada (IIROC) and compares them with its predecessor, the Investment Dealers Association of Canada (IDA). The study collected data from IIROC's tribunal cases decided between June 2008 and December 2019 and compared them with data on the IDA's enforcement of complaints from 1984 to 2008. The findings reveal no statistically significant difference in the fines imposed by the two regulatory bodies. Furthermore, IIROC has refrained from issuing lenient penalties such as retaking examinations/courses or mandating terms and conditions for offenders. The results also indicate no significant impact on the number or distribution of offense types committed in the industry over time. Most notably, the Ontario Securities Commission, the Canadian Securities Regulators, and the new Self-Regulatory Organization of Canada should consider these findings when formulating policies concerning the role of self-regulation in the financial markets.  相似文献

Rural industries in West Bengal are characterized by a multiplicity of organizational forms, such as independent petty production, petty production under subcontracting relations with a master trader, modern small‐scale production, and medium‐sized capitalist production. On the basis of field data, we have estimated the amount of surplus generated by these different kinds of producer across a number of organizations and industries, using an alternative criterion: imputing wages to family labour. It was observed that a large number of petty producers generate negative or very low surpluses, and thus have to find supplementary sources of income. Further, the surpluses generated by petty producers attached to a master trader are generally higher than those of independent petty producers.This can be explained in one of two ways. Either the existence of mutual trust between attached petty producers and a master trader offers the former certain advantages over the independent ones, in terms of steady access to urban markets, cheaper sources of raw materials, and easy credit. Or, alternatively, the control such attachment licenses enables a master trader both to extract and to maintain continuous access to higher levels of surplus. For these reasons, this system, of organization lends viability to artisanal production.  相似文献

This article traces the rise of militancy in Manipur including the Armed Forces Special Powers Act 1958 (AFSPA) and analyses the reasons and its impact on the people. Manipur is one of the Indian states plagued by self-determination movement, inter-ethnic strife, and the militarization of ethnic groups for the last few decades. The Indian Armed Forces, who are specially trained to protect the country against a foreign invasion, are being engaged to combat internal strife with extraordinary powers. This has further worsened the conditions in the state. In the period of 1980 to May 30, 2007, 2,675 civilians and 1,314 militants were killed; while 2,061 civilians were injured and only 865 militants surrendered to the authorities. It can be said that five decades of conflict have greatly undermined the people of Manipur, both physically and spiritually and have threatened the very survival of entire communities.

A plethora of literature has been undertaken to study the validity of the Feldstein–Horioka (FH) puzzle. However, divergent views continue to persist in the FH puzzle literature. This study explores the empirical validity of the FH puzzle in the case of South Asian countries using annual data from 1960 to 2017. Both panel data approach and Markov‐switching regression approach are used to empirically analyze the FH puzzle. The results of the cointegration test confirm the long‐run relationships between saving and investment in the selected South Asian countries. The results of Markov‐switching regression confirm that the saving‐retention coefficient has shifted from high to low values and also from low to high values. Thus, the FH puzzle exists for a particular time period and mostly depends on the regime shifts in the South Asian countries. The results of panel fully modified ordinary least squares (FMOLS) and dynamic ordinary least squares (DOLS) methods also confirm that FH puzzle holds for the South Asian countries. Therefore, the study suggests that any saving promotion policies are desirable for enhancing investment among the South Asian regions.  相似文献
